Before i start, please take it easy on my :D I'm new to the turbo (and Audi for that matter) world. I bought the car a few months ago and have been slowly trying to make it a reliable daily driver. Thanks to all the great DIYs and members here did most of the stuff that went wrong so far myself.

Here is what happened:

My exhaust (i think) came off today while driving, i heard a loud clunk coming from the engine compartment, at first i thought something happened with the engine, it didn't pull anymore and sounded like a boat, then i checked under the hood and see this:

As far as i can tell it looks like it just popped out, how do i need to go about fixing it?

Car is a 97 1.8TQM

Thank you

looks like its a pressure fitting, i would just shove it back in place and maybe get a hose clamp or something and attach it better?

I'm going to try that once the car cools off

I think you'll have to look for a new cat. I would also consider a HFC if i were you.

I would look into doing a complete exhaust system at this time, if you have the funds for it. With a HFC included, you can have a full cat back exhaust system for $750 tops installed.

I'm in Michigan, so no emissions testing. If i can't get it to work then i'll just get a test pipe, cheaper too ;)

yeah this happens ALL the time, you have a couple options: weld it(preferably remove it and take it to a exhaust shop) or do the smart thing and but a high flow cat for about half the price of a new one for like 250 or a test pipe for even cheaper http://www.labreemotorsports.com/products_vw.html

Been looking around a bit for a test pipe. How is this one? http://www.ecstuning.com/Audi-B5_A4-Quattro-1.8T/Exhaust/ECS/ seems like a good price for one.

That will work but that is still a test pipe, for test or track use only, no smog test in your state don't mean you can run with not cat, if you got pull over they see you are not running a cat, the fine is going to be big. Just spend a little more now and do the right thing.

same exact thing happened to me. grab a test pipe from ebay for 90 bucks (i think it was) and be done with it.

Yup that's exactly the same. It is barely drivable.

I just looked at how to remove everything (looked at the DIY), it looks like a pita... checked all my bolts and can barely get to them with the tools that i have.

Have you done it yourself? If so, any tips for a newbie?

I've done it myself (and with help) but you're gonna want to remove the airbox to get to the nuts holding the downpipe to the turbo and then remove the nuts holding it to the rest of the exhaust system. It's a serious pita to get to the bottom half but the higher off the ground you get it the easier it is to get everything undone. Especially when you're bending over the engine bay.

I had the downpipe break away from the flange there and just welded it back together myself (actually my guru uncle did it), but I'm sure nearly any shop would be more than willing to do a simple weld.

That happened to me on the highway one day, when i got it home, i just took the cat section out and welded it back together and then hollowed out the cat since it was out, then did the anti fouler mod for no cel

My brother bottomed my car out going 80 over a hill. Also had to replace my tranny pan. One grand from the stealership.

Well... none of the bolts want to remove so i PB Blasted them now, hopefully tomorrow will be more productive.

I did install my testpipe but I worked at a dealer at the time and had lift access + all the power tools in the world so it was just a matter of taking the cat out of the bay.

Definetly need to remove the airbox, you take the cat out through the top of the engine bay.

I didn't even disconnect the downpipe until it and the cat were out of the car.

The bolts were a pita to get out for me too , we used a lot of methods for removing them, eventually a snap-on 900lb air gun did the trick after pb blaster and a torch.

See that's where i'm stuck right now. I can't get the lower bolt off, so i'm trying to get the cat and the dp + flexpipe through the engine bay out, but i can't get enough clearance to get the holding bracket. I think i'm just going to cut the cat with a saw and then remove it.
